The Dunedin to Brighton veteran vehicle run will celebrate its 60th year in January.
Convener Tony Devereux said it was the oldest veteran vehicle run in the southern hemisphere.
''So it's got a bit of status from the veteran vehicle fraternity.''
And more than just cars enter the run, including motorcycles and trucks.
To qualify for entry, a vehicle must be built before 1919. The 1910 Humber that won the first run in 1955 would feature again on January 25, he said, as would the 1900 Wolseley that had featured in every run.
The vehicles would be in the Octagon for an hour from 10am on the day, where a band would play, before the vehicles travelled to Brighton.
Dunedin Mayor Dave Cull would flag the cars away and veteran broadcaster and car enthusiast Dougal Stevenson would provide a running commentary, Mr Devereux said.
Most drivers and navigators would be dressed in period Edwardian and Victorian costumes.
''That makes quite a spectacle.''
The convoy would travel up South Rd and through Concord to the Brighton Domain, where ''amusing'' field tests would be held until 3pm.
The Brighton Gala was on the same day, Mr Devereux said.
The propeller failure of an Interislander ferry could make transporting vehicles from the North Island difficult so it was hard to predict entrant numbers, but Mr Devereux expected the event to be ''big''.
Last year, the cruise ships in Dunedin had the crowd ''overflowing'' on to the street to watch the vehicles depart from the Octagon.
''We were a bit shaken at how the crowds were standing out in front, taking photos of the vehicles coming towards them. It was uncomfortable - I didn't like it all.''
The crowd would be easier to manage in January because there were no cruise ships due but spectators should keep out of the path of vehicles.
''They don't stop - and folk have no idea - you can't pull them up. If it has been raining, you've got zero brakes.''
